A city clerk RDS database needs solid baseline performance but does not require provisioned io2-level IOPS. Which storage choice best balances cost and capability?
Select an answer to reveal the explanation.
Short Explanation
Buy the tool that fits the job. gp3 covers most clerk workloads; io2 is the specialty wrench when metrics prove you need it.
Full Explanation
RDS gp3 provides cost-effective SSD performance with configurable IOPS and throughput for many workloads that do not need io2. Defaulting every database to io2 raises storage cost without measured benefit. Glacier is cold object storage, not primary relational storage. Instance store without managed backups sacrifices durability inappropriate for clerk records.
